Stir together the first 4 ingredients in a small bowl. Sprinkle over chicken. Place chicken in a single layer in a lightly greased 6-qt. slow cooker.

Whisk together cola, ketchup, brown sugar, vinegar and bourbon in a small bowl. Slowly pour mixture between chicken pieces (to avoid removing spices from chicken). Place lemon slices in a single layer on top of chicken.

Cover and cook on high for 5 hours or on low for 7 hours. Remove chicken from slow cooker; let cool slightly. Discard lemon slices. Skin, bone and shred chicken. Serve on your favorite bread for sandwiches with coleslaw.
